DESCRIPTION

The OPA237 op amp family is one of Burr-Brown’s

Micro

Amplifier

tion to small size, these devices feature low offset

voltage, low quiescent current, low bias current, and a

wide supply range. Single, dual, and quad versions

have identical specifications for maximum design flex-

ibility. They are ideal for single supply, battery oper-

ated, and space-limited applications, such as PCMCIA

cards and other portable instruments.

OPA237 series op amps can operate from either single

or dual supplies. When operated from a single supply,

the input common-mode range extends below ground

and the output can swing to within 10mV of ground.

Dual and quad designs feature completely indepen-

dent circuitry for lowest crosstalk and freedom from

interaction.

Single, dual, and quad are offered in space-saving

surface-mount packages. The single version is available

in the ultra-miniature 5-lead SOT-23-5 and SO-8 sur-

face-mount. The dual version comes in a miniature

MSOP-8 and SO-8 surface-mount. The quad is avail-

able in an SSOP-16. The SSOP-16 has the same body

size as an SO-8 with 16 leads, while the MSOP-8 has the

same lead count as a SO-8 but half the size. The

SOT-23-5 is even smaller at one-fourth the size of an

SO-8. All are specified for –40

°C to +85°C operation. A

macromodel is available for design analysis.
